SHIP PROPULSION AND THE LIKE.

To all whom it may concern: i

Be it known that I, GLOVER ORIN PARKER, a citizen of the United States, residing at Bentonville, in the county of Benton and State" of Arkansas, have invented certain new and useful Improvements in Ship Pro pulsion and the like, of which thefollowing is a specification, reference being had therein to the accompanying drawing.

This inventionrelates to power development utilizable for various purposes, such as the propulsion of boats, aerial ships, aeroplanes, etc.

The object of the invention is to provide for the development of power for propulsion and other purposes, which consists in effecting movement of a power-creating instrumentality in a fluid in such manner as to create a force whereby a highdegree of Inomentum'is produced. I

A further object of the invention is to provide, in a simple and compact structure, an aggroupment of components adapted to be moved through a fluid, such as the atmosphere, water, etc., at least one of the components bein movable in such manner as to develop a force upon the fluid, whereby the structure, in its entirety, may be propelled.

Still another object of the invention is to provide a structure comprising an aggroupment of instrumentalities, in one of which is housed driving mechanism adaptedto be mechanically connected with the other instrumentality, constituting a driven component, so that the latter maybe rotated in a fluid in such manner that the fluid may pass through the driven component and develop a force for the propulsion of the structure through the fluid.

Broadly, the invention resides in a, buoyant body and a revolving body having a discharge opening of greater diameter than the inlet, whereby the fluid may be introduced into the inlet and discharged at the outlet at an augmented velocity.

More specifically, the invention resides in introducing a fluid into the smaller end of a frustrated cone and discharging it at the larger end thereof at an augmented velocity.

The invention seeks, in general, to provide for the propulsion of a buoyant body through a fluid at hi h speed, thisbeing attained by rotating a ollow, frustrated cone and introducin a fluid into the smaller end Specification of Letters Patent. Patented June 4, 1918, Application filed March 25, 1915. Serial No. 16,990.

thereof and discharging said fluid at the larger end at an augmented velocity.

Otherobjects and advantages are present 1n theinvention and these will be obvious from the accompanying drawings and also from the following description.

In order that the invention may be comprehended, drawings are hereto appended which are illustrative of various possible embodiments and utilizations thereof; but it is to be understood that these are illustrative and that the invention is susceptible of a Wide range of modification and is capable of embodiments and utilizations other than those disclosed.

In these drawings:

Figure 1 is a view in perspective of a boat with the invention applied thereto;

Fig. 2 is a view in vertical longitudinal section thereof;

Fig. 3 is a view, in longitudinal section, on an enlarged scale, of the propelling instrumentality, detached from the boat;

Fig. a is a view in vertical transverse section thereof; y

Figs. 5 to 8 are detail views of certain modifications of the propeller; and t Fig. 9 is a view in perspective of an aeroplane provided with the invention.

In these drawings, the referencemumeral 1 designates the hull of a boat which, in this instance, is more or less cylindrical. The hull is provided with a cockpit 2 of any appropriate form and construction.

The rear portion 4 of the hullis preferably conical and considerably elongated, as shown. In practice, it is found to be of ad vantage to make the conical portion 4 hollow, andmay be filled with ballast, if desired.

The forward portion 3 of the hull is in the form of a truncated cone and preferably is also hollow. Between the body portion of the hull and the front and rear portions 3 and 4. are bulkheads 5 and 6, of any desired kind.

The forward conical portion 3 also is provided with a bulkhead Disposed within the boat is an engine or motor 8 that may be of any appropriate character, and to this is attached a transmission shaft 9 which extends through the conical portion 3 and rojects beyond the same.

, end 15 of the propeller.

Mounted on the forward end of the shaft is a propeller 10 that is of a particular construction: As shown in Figs. 1 to 3, which embody thei'nvention in one of its aspects, the propeller includes a frustrated "cone, designated 11. Within this is mounted an internal frustrated cone 12. Between the two cones are division members 13. The shaft "is secured to the inner cone,"and "the division members constitute a rigid connection between the two cones. They also have additional functions which will presently be pointed out.

i It is the desideratum of my invention to ntrodu e t e l id in o h rw end of-the propeller 10 and discharge it at the rear end 15. It will be observed that this rear end of the cone is of a diameter greater han the e niea port n. 10i the h l A rudder 16 is suitably disposed on the portions: and operated by the usual tiller ropes 17 which are actuated by a hand-wheel 18 di posed i th oc pit he operation of the structure is as fol- QW$= The eng ne h i g b en tar ed, h propeller 10 is thereby set in motion, with i the result that the fluid which has entered th rward he w ll m ve' tween the surfaces of the two cones 11 and 1 2 and'between the division plates and discharge, in a tangential direction, at the rear In so doing, the fiuid i mP. ,'W bh 0 i'esrwar y n st h b y of l id whi h orma y would surround the conical portion 8. When the speed of the propeller and the flow of the fluid have reached a certain de gree the impingement of; the fluid that has flowed through the propeller effects a reactive force on the fluid surrounding the portion 4, and this produces a high degree of momentum of the boat and propels it. Th e. t n i ra i pl men f h fluid from around the forward portion of the boat resulting from the action of the fluid through the propeller, so that, as this fluid tends to move back against the hull, it W ith great Pr u en mp the. conical portion 4; and, by its pushing effect thereon, augment the action ofthe propeller in drawing the boat forward. I

VYhile, in the foregoing description, the operation of the structure has been set forth in connection with the movement of a body through water as thefiuid; yet it is tobe understood; th the. nven n. i pa 3 being operated in the air, as the fluid. Therefore, in Fig. 9, the utilization of the invention is disclosedvin connection with an aeroplane. Generally speaking, the opera tionofIthe propeller, in this instance, is the same as that describedin connection with the bpatr tru t Injlfig. 5, there is illustrated a fluid-controlling device that may, if deemed essential or advisable, be mounted so that it will move through the fluid in advance of the propellerfTliis includes a conical casing 19 provided with a series of apertures 2'Ofand disposed upon the forward'end of'the propeller itself. Mounted on the forward end of an inner shaft 22-the main shaft 23, in this instance, being hollow-is a conical member 21adapted to be moved in relation to the inner walls of said member 19. Means are provided for effecting its movement and these include. a 's'haft shiftin'g mechanism 24 disposed within the cockpit and comprisin ascrew-shaft 25 rotatable in stationary bearings 26 secured in the cockpit and adaptedto actuate a' bracket 2'Z- into which the shaft is threadedearried at the end of theshaft'25. and connected to a collar 28. which encircles the main shaft 23 and connects with the shaft 22. By this means, the shaft 22 may be given a longitudinal movement so that the conical member 21 can be positioned in relation tothe inner walls of the cone 19. Its relative position with respect to said inner walls will determine the amount of inflow of fluid into the cone 19 and, thus, into the propeller. If it is positioned against said inner surface, it will cut oil allinflow and thereby. prevent operation of the propeller, On the other hand, if it is positioned remotely from said inner surface,'a considerable volume of water can pass into the structure and, in this way, a large volume of waterbe introduced into the propeller, with consequent augmented action thereof: inthe manner al ready explained...

v In Figs. 6 to 8,, modified forms of structure are illustrated Fig. 6 shows. a propeller having. an elongated portion, With a conical ortion. In Fig. 7;, there 'isd-isclosed a form of propeller in which the division members are curved, and whereby, imder certain conditions, the, action il the propeller. is facilitated andthe power, thereby developed increased.

In Fig. 8, a propeller. with. an outwardly.- flared curved! surface is presented. In. some instances, thesemodified forms of propellers may be found to be desirableand. effective.

ft is to be understood, as already pointed out, that the invention is susceptible of-even greater modification; wherefore, it will be seen that what is herein disclosed is merely illustrative and" is'not to be regarded as indicatingthelimits of the invention.
